Abstract

See full text

A DC voltage converter apparatus is provided to convert a fluctuating input DC voltage into an isolated and regulated output DC voltage by operation of a first switch device for charging a capacitor through one primary winding of a transformer and a second switch device for discharging the capacitor through a second primary winding of that transformer. A load is energized by an output voltage from a first secondary winding when the first switch is conducting and is energized by an output voltage from a second secondary winding when the second switch is conducting. The first and second switching devices are controlled in response to the voltage change across the capacitor.
